From acda2b793f69c6e0e9b9667e9ebe8a0325eb5ecd Mon Sep 17 00:00:00 2001 From: Gergely Nagy Date: Thu, 1 Sep 2016 08:32:47 +0200 Subject: tap-dance: Do not start a sequence on keyup There was an odd case, which confused the hell out of tap-dance: suppose you had a number of tap-dance keys, on a layer, and as part of the tap-dance, you turned that layer off - or had it on one-shot to begin with. In this case, the keydown event would trigger the tap-dance key, but the keyup would not. This had two funky consequences: - tap-dance did not correctly register that the dance has ended. - pressing any other tap-dance key would interrupt the previous tap-dance, and potentially input unwanted characters. To fix this, we simply do not start a tap-dance sequence on keyup, only when it is pressed. This way the previous sequence has enough time to time-out and finish properly, and we don't get confused. This fixes algernon/ergodox-layout#107.
